To solve the problem of high latency and packet loss rate in Mobile IP protocol s handoff process,a Dual-link mobile IP system implementation based on link layer trigger is presented,namely,use link layer trigger to start network-handoff in advance,and use link redundancy to prevent packet loss,and consequently achieve the purpose of seamless handoff.

A trigger circuit of multi-stage reconnection electromagnetic launch system;

Trigger circuit of data acquisition system in particle track system and its position resolution;

Thyristor linear trigger circuit under the variable power frequency;
